I am using Joplin for all my knowledge articles and notes. Available for all main desktop and mobile OS's. Great Evernote replacement with good Webclipper. Notes can be edited in Markdown. Syncing to Nextcloud, Dropbox, Onedrive, Webdav. And fully open-source. Currently a few 1000 notes, searchable or browsable via notebooks or tags.
Very keen to try it out, but just running the windows .exe does not work. Also adding the dll does not help. I guess they want to limit their users to real experts till now. Really a pity.
Actually not in a home server, since it is in the cloud, but still...
